I do have /proc/timer_stats, but it provides nothing interesting:
$ cat /proc/timer_stats
Timer Stats Version: v0.2
Sample period: 0.000 s

Ah well. And yes, you are correct that I'm not in the habit of compiling kernel updates. I suspect I'd have to move to a more tinker-friendly distro to make that a reality.
I have to admit, I got out of the habit of compiling my own kernels just a bit before it got popular for distros to wrap a bunch of magic up in the kernel build process--initrd and all these related toys. I think the last "customized" kernel I compiled and booted was an early 2.6 series kernel, pre 2.6.9. The stock distro kernel has been "good enough" for almost a decade, if not more.
Perhaps I'm just being a wuss or maybe I just don't care enough, but the last time I tried compiling a custom kernel on one of my machines, I eventually ran away screaming. That was only after a day or two of fighting with it that I finally gave up and went back to a vender kernel.
(The last two times I believe I tried this were on RedHat 8 or 9 (pre-Fedora) and Ubuntu. Something tells me if I tried this, say, on Slackware or even Debian, I would be telling a different story.)
